Drably colored at rest, a Belching Gasper inflates its anterior and displays an intense warning pattern - varied from individual to individual - before its innermost worm lets loose a stream of its natural nerve gas, which remains poisonous for several seconds on contact with air. It is the only Gasper to possess eyes, necessary to gauge the concentration of toxins it may require for an adversary's mass.
Toothless, the Belching Gasper's "lips" are tough and strong enough to tear pieces from larger prey with some effort, but it generally prefers smaller meals.
The Belching Gasper conducts itself more politely than the common Snapping Gasper, minding its own business until it feels threatened. Once spurred to combat, however, it takes pleasure in observing the effects of its poison, and is usually convinced that its poison is the "best" of its kind.
Belching Gaspers can spray their toxins in a thin, powerful stream up to a distance of thirty to fifty feet, or spray the immediate area in a single, massive cloud. The gas ceases to be toxic after less than half a minute, but may continue to smell highly unpleasant and reduce surrounding visibility, providing useful cover to allies or further disorienting creatures who resist paralysis.
COLONIAL MIND: the monster's consciousness is distributed across multiple organisms, giving it immunity to mind-altering substances and psychowave attacks.
NERVE GAS: the Belching Gasper breathes a paralyzing poisonous gas, which lingers as a noxious, blinding fog long after it loses its toxicity.
